High-Performance SaaS & Cloud Architecture
Welcome to my engineering portfolio. I specialize in building secure multi-tenant SaaS platforms, saving cloud costs through optimized AWS serverless/container architectures, and writing robust platform integrations.
Production System Breakdowns
B2B Financial Portal Takeover
Migrated database from SQLite to RDS PostgreSQL, set up ECS Fargate cluster under ALB, and built Redis caching layer to handle high concurrency under a strict $100/mo AWS budget.
AI SaaS Marketing Platform
Designed multi-tenant Turborepo monorepo with 6 apps and 55 data models, integrating dual payment gateways (Stripe + WeChat Pay) and a custom multi-LLM router.
WeChat Mini Game RPG Engine
Developed a 100% configuration-driven game core loop decoupled from scene positioning. Integrated remote sub-packaging rules and serverless cloud billing synchronization.
Next.js SaaS Starter
A production-grade Next.js SaaS template with a custom Multi-LLM AI Router, authentication, comprehensive dashboard, Prisma ORM, and Tailwind CSS.
KOL Match Engine
High-concurrency Spring Boot 3 engine using cosine-similarity scoring across 4 dimensions, backed by Redis and RabbitMQ.
